My puppy was vaccinated by a local vet against parvo with the RECOMBITECK C4/CV vaccine at 4 week intervals per the vets reommendation. It was vaccinated a total of 3 times for parvo per the vets recommendation. It was 111 days old when the last parvo shot was given. The puppy died when it was 6.5 weeks old of parvo despite treatment. Has anyone had a similar experience?
